HARVEY D. FARRIS, OF SPOKANE, WASHINGTON.

WATER-CLOSET BOWL.

To all whom it may concern:

Be it known that I, HARVEY D. FARRIs, a citizen of the United States, residing at Spokane, in the county of Spokane'and State of Vashington, have invented certain new and useful Improvements in \Vater- Closet Bowls, of which the following is a specification.

This invention relates to improvements in water closet bowls and moreparticularly to improvements in the safety overflow de* vices of such a bowl, this application constituting a division of my application filed April 7, 1919, Serial No. 288,179.

Various improvements have been proposed for preventing the overflow of a water closet bowl when the siphon leg thereof becomes clogged. For example, in one type of bowl there is provided, in the forward wall, an ascending overflow leg and a descending leg, the first mentioned leg opening at its lower end into the bowl at a point forwardly of and opposite the intake end of the siphon leg and close to the bottom of the bowl. In such a construction it is presumed that in the event the siphon leg becomes clogged and the water level in the bowl reaches the juncture of the ascending and descending legs of the overflow, any additional volume of water entering the bowl will rise through the ascending leg and flow downwardly through the descending leg and, of course, thence to the down pipe. Theoretically such a construc-' tion is practicable but I have found that in actual use it frequently will not operate as intended. For example, it is a well known fact that the excrement deposited inthe bottom of the bowl is not immediately carried upwardly into and through the siphon leg when the! bowl is flushed but will first be carried back and forth several times before being caused to enter the said siphon leg. As the excrement is washed back and forth in the bottom of the bowl a greater or less quantity thereof is almost certain to' become lodged in the ascending leg of the overflow system, with the result that in time this leg will become clogged without this fact, however, being -made apparent. Then, should the siphon leg become clogged the bowl, when flushed, will be flooded and will overflow because of the inability of the overflow system to take care of the surplus water. It is, therefore, another important Specification of Letters Patent.

Patented June 1; 1920.

Serial No. 288,179. Divided and this application filed July 24, 1919. Serial No. 313,096.

object of the present invention to provide in a water closet bowl, a novel arrangement of .safety overflow legs, the arrangement being such as to insure against clogging of the ascending leg or legs and to provide for the proper overflow of water even in the event one ofthe ascending legs should become clogged. I

In the accompanying drawings:

Figure 1 is a perspective view of a water the present invention;

Fig. '2 is a horizontal sectional view therethrough taken in a plane above the upper ends of the ascending and descending legs of the overflow system;

Fig. 3 is a vertical front to rear sectiona view through the bowl.

In the drawings the numeral 1 indicates In general a water closet bowl having the usual flushing channel 2 surrounding its upper margin and provided near its top at 1ts rear side with the usual outlet flushing spout 3 through which water is to be discharged in a downward direction to flow over the bottom of the interior of the bowl so as to carry off the excrement through the upwardly and forwardly inclined siphon leg 4, the excrement passing through the down passage 5 and out through the discharge 85 opening 6 with which is connected the down pipe (not shown).

I will now describe in detail the means provided for preventing flooding and overflow of the bowl. As clearly illustrated in 90 Figs. 1, 2 and 3 of the drawings, the bowl located below the supply passage for the 100 flushing spout 3. At each side of the descending overflow leg 27, the bowl is formed in its rear. wall with an ascending overflow leg 29, and these legs 29 extend downwardly" and in a general forward direction about the 105 sides of the bowl at the rear thereof and communicate at their lower ends by way of the openings 30 with the interior of the bowlnear the bottom thereof. At their upper ends, these legs communicate with the 110 closet bowl constructed in accordance with overflow into the descending leg 27 and will pass downwardly through said leg and-out through the discharge passage 6. Referring particularly to Fig. 2 of the drawings, it Will be observed that the openings 30 are located at opposite sides of the bottom of the interior of the bowl and consequently at opposite sides of the intake or lower end of the-siphon leg 4. As a consequence, even though the deposited excrement be washed back and forth over the bottom of the bowl before beingcarried upwardly through the siphon leg 4, none will move over the openings 30 and consequently there is little likelihood of the deposited excrement entering the ascending overflow legs 29. Should the siphon leg 4 become clogged, water will, of course, flow upwardly through the legs '29 into. the chamber 28 and thence downwardly through the leg 27 and out through the pipe 6, so as to prevent flooding of the bowl, and this will take place even though one of the legs 29 should become clogged, although due to the disposition of the openings 30, this is extremely unlikely to occur.

Having thus described the invention, what is claimed as new is:

1. A water closet bowl having an outlet, a descending overflow leg in communication with the outlet, and an ascending overflow leg in communication with the upper end of the descending leg and communicating with the interior of the bowl through the bottom thereof at one sideof the front to rear middle line of said bottom.

2. A water closet bowl having an outlet, a descending overflow leg communicating with the outlet, the bowl having a chamber in communication with the upper end of the said descending leg, and an ascending overfiowleg at each side of the descending leg, the ascending legs communicating at their upper ends with the said chamber and at .their lower ends with the interior of the bowl through the bottom thereof at opposite sides of the front to rear center line of the said bowl.

3. A water closet bowl having a siphon discharge leg inclined upwardly and forwardly from its bottom and having a discharge branch extending downwardly to the outlet from the bowl, the bowl having a water inlet at the rear side of its interior arranged to discharge water downwardly and forwardly in the direction of the intake end of the said siphon leg, a descending overflow leg in communication with the out- HARVEY n.
